About Me [CV]

Hi, I am a second-year Ph.D. student in Fudan University & SII (Joint Program). I received my B.S. in Computer Science from Fudan University. I conduct research on Multimodal LLMs and LLM agents. I currently work with Pengfei Liu in SII. Previously, I worked with Qi Zhang, Fei Liu, and Jiaqi Wang.

Please feel free to contact me for discussion and collaboration!
